An army sergeant walks into a drugstore and places a ragged condom on the counter.
“How much to repair this?”, he asks.
The pharmacist looks over the condom, saying “It’s ripped in a couple of places, and there are several holes in it, but it’s repairable. But honestly, I’d just replace it with a new one”.
The sergeant said he’d have to go away and think it over.
Later that day he returned. “After much discussion”, he said to the pharmacist, “The regiment has decided to invest in a new one!”.
